We have a Mac Pro with an internal 1TB backup drive that was working fine but now has suddenly stopped showing on the desktop. When we run Disk Utility it says the drive is not mounted and we get the error message "Disk Utility can't repair this disk. Back up as many of your files as possible, reformat your disk, and restore your backed up files."


Our question is: How do we back up the files when we cannot access the drive?


We have tried moving the drive into another bay and this has had no effect.


Any help will be greatly appreciated!

    Well you need to install the OS to another drive if you didn't have a clone of the system already.


    Ideally put it in a FW external case so you can turn it on and try to work with it. The best candidate is $90 Alsoft Disk Warrior.


    Data Rescue 3 is $90 also has a demo and rescue or scavange files to another drive. The demo lets you get to see if it can do anything.


    New boot drive or your DVD.

    Recovery drive to backup onto.

    New system drive.

    After recovering files you would want to reinitialize and zero the old drive.


    You can't fix a drive w/o having another boot drive or using Recovery mode on another drive or OS X SL DVD.


    Carbon Copy Cloner and TimeMachine are a good combo. It will also clone the recovery partition in Lion as well.


    A small system maintenance emergency partition of 30GB for just OS (can even be on TimeMachine drive) is almost essential. Recovery Partition would be better if it were not on the same drive (laptops with only one, maybe).

    If this is only your backup, do not invest a lot of time on it.


    Buy a New (and probably larger) drive, and make a new backup of your original files on the new drive, and go forward with the new drive as your Backup.


    Once you have a working backup again, you can Zero the old backup drive and decide whether it can still be serviceable.
